eGFR (Estimated Glomerular Filtration Rate) 113 mL/min/1.73m² in Men, Women, Elderly, and Kids

An eGFR (Estimated Glomerular Filtration Rate) of 113 mL/min/1.73m² can be interpreted somewhat differently across various age groups and sexes, though it consistently represents excellent function and places kidney health far from concerning levels. In younger adults, particularly men, this value might be quite common and reflects optimal kidney performance, showing the kidneys are robustly clearing waste. For women, kidney function might naturally be slightly different due to physiological variations, but 113 still signifies exceptional health and strong filtration capacity. As people age, it's natural for eGFR to gradually decrease, reflecting a normal part of the aging process. Therefore, an eGFR of 113 mL/min/1.73m² in an older adult, say someone in their 70s or 80s, would be considered exceptionally high and remarkable, indicating their kidneys are functioning at a level more typically seen in much younger individuals, which is a significant health advantage. In children, eGFR calculations are often adjusted for growth and development, and a reading of 113 would likewise indicate excellent kidney health, ensuring proper growth and waste removal. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) highlights how important it is to consider age, sex, and body size when interpreting eGFR values to provide the most accurate health picture. Regardless of demographic, this specific eGFR number stands as a very strong indicator of healthy, efficient kidneys, showcasing their ability to filter and maintain the body’s internal balance effectively and demonstrating a low risk for kidney-related complications.

Medicine Effects on eGFR (Estimated Glomerular Filtration Rate) 113 mL/min/1.73m²

When your eGFR (Estimated Glomerular Filtration Rate) is 113 mL/min/1.73m², it indicates excellent kidney health, meaning your kidneys are very efficient at processing and eliminating substances, including medications. Most commonly prescribed medicines are dosed assuming healthy kidney function, and your eGFR suggests your body handles typical drug elimination effectively. This means you are likely to clear medications as expected, reducing the risk of drug buildup. However, it's still important to be aware that certain medications, even those used for common conditions, can impact kidney function over time, especially with long-term use or in specific situations.
